Patent GB-440817-A (GB)
Abstract: 440,817. Recording rest or motion. SPEEDOMETERS PERMANENT RECORD, Ltd., and JANITCH, E. M., 68, Victoria Street, Westminster. July 19, 1934, No. 21160. [Class 106 (iii)] In a recording-instrument in which a stylus marks on a clockwork driven card when a vehicle or other apparatus is in operation, mechanism is actuated in accordance with the distance travelled to move a stylus backwards and forwards through a determined distance at right angles to the travel of the chart and means are provided to ensure that the stylus records only when the engine is running. The shaft B<1> driven by the clockwork mechanism B is hollow and provided with a flange B<2> against which is clamped by a nut B <6> a toothed wheel B<3>, a distance piece B<4> and a disc B<5>. The winding shaft B<7> passes freely through the shaft B<6>. The disc B<5> is provided with pins C<1>, C<2> of different diameters to receive an annular chart C always in the same relative position. A plate A<2> behind the chart carries a time scale D over which moves a pointer B<8> on the disc B<5>. Two styli E, F pass through slots in the plate A<2> and act on the chart, a rigid back plate A<3> being provided. The stylus E is mounted on a spring arm E <1> attached to a lever E<2> pivoted at E<3> and carrying a pin E<4> engaged by the forked end of a spring-pulled lever G pivoted at G', the other end G<2> of the lever engaging the teeth of the wheel B<3>, which on rotating oscillates the arm E<1> and causes the stylus to oscillate at right angles to the movement of the chart. Mounted behind the stylus E is a pivoted weighted lever H held away from the stylus by a spring. With the vibration of the vehicle the lever strikes the stylus and causes it to mark the chart. The stylus F acts continuously on the chart and is carried on a pivoted lever F<1> which can be manually moved from outside the casing to take up either of two positions in which it is held by a spring F<2>. In a modification, the toothed wheel B<3> is omitted and the stylus E oscillated by a grooved cam driven by worm gear from the odometer mechanism.

Abstract: 1,234,782. Fibrillating orientated strips and films. COURTAULDS Ltd. 3 Oct., 1968 [4 Oct., 1967], No. 45108/67. Heading B5B. An orientated strip or film of a crystalline polymeric material which has been longitudinally orientated to render it fibrillatable is fibrillated by moving it longitudinally past a plurality of fluid jets together extending trans. versely of the moving strip or film and directed at the strip or film. The fluid jets may issue from one or more lines of jet holes aligned transversely across the strip or film. Each line of jet holes may extend across the whole width of the strip or film and may be aligned at right angles to the longitudinal axis of the strip or film. The strip or film may be held under tension against the jet holes as it is moved past them. The fluid jets may be liquid or gaseous but are conveniently jets of air issuing from a line of jet holes aligned transversely across the strip or film. The strip or film may be made of polypropylene. The fibrillated strip or film may be twisted to form a twine or may be chopped transversely to form staple fibres. In the illustrated example a strip 1 (Figs. 1 and 2) of transparent crystalline polypropylene film is stretched in the longitudinal direction at a stretch ratio of 10 : 1 at a temperature of 150‹ C. to a stretched size of 0À5 inch width and 0À002 inch thickness. The strip is then passed in the direction of the arrow A over the face 2 of a jet head 3 at a speed of 100 metres per minute, being pressed against the face 2 by the tensioning rollers 4 and 5. At the same time air at a pressure of 40 p.s.i. is passed into the chamber 6 of the jet head 3 through inlet pipe 7 and emerges from the chamber 6 through two lines of jet holes 8 and 9 in the face 2 as a series of air jets. The holes are 0À005 inch in diameter and are spaced apart in each line by 0À01 inch. As the strip 1 is passed over the lines of holes 8 and 9, the air jets burst through the readily fibrillatable strip to cause the formation of a series of longitudinal splits 10 in the strip.

A method of producing frozen fish fillets of flatfish such as plaice, comprises the steps of cutting from the skin and the bones of each fish an under fillet and an upper fillet of substantially identical contours, allowing the pair of fillets cut from each fish to drain until they are in a slightly moist state, placing the pair of fillets of each fish together with the sides thereof from which the bones have been cut facing each other and with the base of the tail of the upper fillet lying exactly on top of the base of the tail of the under fillet, compressing the pair of fillets to expel air from between the fillets, and subsequently deep-freezing each pair of fillets just for sufficient time to allow the whole mass of fish of each pair of fillets to be thoroughly frozen and form an integral unit that is in the form of a bonefree fish. The freezing step may be carried out in a refrigerated tunnel, the pairs of fish fillets being subjected, in the tunnel, to a temperature of the order of 35‹C. below zero for a period of time of the order of two hours. After freezing, the pairs of fish fillets may be beaten slightly and covered with a layer of bread crumbs.

Abstract: 459,181. Electric signalling systems. SMITH, A. J. M., and GANE, R., Low Temperature Research Station, Downing Street, Cambridge. July 4, 1935, No. 19161. [Class 40 (i)] The temperature, and oxygen and carbon dioxide content of gases are determined electrically by Wheatstone bridge means, a battery and galvanometer being common and valve and switch devices being provided to select the gas to be tested and the nature of the test to be applied. As shown in Fig. 2, a number of thermometric devices 17, 18, 19 are wired to the contacts of a double-pole selector switch B by setting which the device desired can be put into one arm of a bridge, another arm being constituted by adjustable resistances 16. The other arms consist of a slide wire 44 tapped by a pointer 43 wired to a galvanometer D. In order to measure the percentage of oxygen or carbon dioxide a conductivity meter 51 and a slide wire 69 and pointer 64 are connected with the battery 47 and galvanometer D in place of the temperature-measuring means by shifting a rotary switch A. An ammeter 56 and variable resistance 55 are also brought in series with the battery. If desired, the measuring current may be alternating and superposed on the heating current for the conductivity meter. Fig. 3 shows a lay-out for enabling the apparatus to test for content of gases in pipe lines X<1> . . . X<6>. A pump 75 first sweeps out the selected line, the valve P being in position P<1>. The valve is then turned to position P<2> so that the gas is drawn through a filter 70, flow meter 71, drier 72, filter 73, needle valve 74, the meter tube M<1>, cock Q in position Q<2>, absorption tube W to remove the CO2, filter 76 and meter tube M<2>., The pointer is now moved to get balance when it then shows percentage of carbon dioxide in the gas under test. In order to determine the oxygen content the cock is put into position Q<3> so that the gas is drawn through tube M<1>, furnace Y for removing the oxygen, filter 77 and tube M<2>, the adjusted position of pointer 64 thereupon showing percentage of oxygen.
